Rear disc brake conversion

Does anyone have any photos of a standard commando pre MK3 footrest/brake pedal setup that's been converted to rear disc brake?
I'd like some ideas on the master cylinder mounting
Cheers

Converting the 850 Mk111 to Right hand gearchange

I've been thinking for some time that I'd like to swap my Mk111's foot controls over to the proper Norton side and the fact that I'm now regularly riding an older Norton is pushing me in the direction of doing it as a winter project. I'm looking to keep the original Roadster riding position...

Rear hub drum to disc conversion

For me, the motivation to loose the rear drum setup is a functional cush drive and loosing a lot of unsprung weight. And a predictable rear brake for wet weather braking is always nice.

Rear disc conversion

Are there kits to do this to my 74'. I have been playing Russian roulette for too many years with these brakes. This winter it gets a new suspension upgrade, front to back and brake upgrade too. Would like to have rear discs. Guido

That's the sort of thing I'm looking for thankyou
Looks like most use a cable operated master cylinder
I'd rather not use a cable unless I have too

The reason for the question is I'm considering going from my current rear sets back to standard position footrests

When I converted my MK111 to r/h gear, l/h brake, I used a standard pre-Mk111 brake pedal that connected via a cable to the 16mm master cylinder under the seat.
It works well and feels normal, as all my other bikes are orientated that way.

Here's what I came up with using Mk III parts; Biggest pita was the long hydraulic line. I made several attempts at using the stock brake lever but in the end, had to fab one up as the cast iron does not take kindly to heating and bending.




















The rear of the Mk III peg arm was cut just behind the M/C mount bolts. A tapered peg section was welded to the leftover after it was ground and cut down to a simple triangle. Then the works was bolted on to the tapered peg. Rechroming wasn't too expensive, but as I said, the lever got fixed and replated twice before I abandoned it and I just made one to suit. First pic was shot before it made it to the plater.
